Abstract: An occlusion device for implantation within a body lumen includes a distal end, a proximal end, and an expandable member extending from the distal end to the proximal end. The expandable tubular member defines a passageway extending from the distal end to the proximal end. The expandable tubular member includes a plurality of struts that are joined to adjacent struts to form a plurality of closed shapes each defining a closed path. The plurality of struts are joined to form a plurality of fixed joints so that adjacent struts are pivotable around respective one of the fixed joints when an external force is applied to the expandable tubular member. The tubular member defines an ellipsoid shape.

Abstract: An endovascular device tip assembly and method of making the same, incorporating a radiopaque marker usable with catheters and other suitable endovascular devices is provided. The tip assembly incorporates a radiopaque marker device by providing a counterbore within a primary bore of a tubular tip of an endovascular device. The marker device is fitted securely within the counterbore and the tubular tip is further deformed distally of the marker in order to secure the marker within the device.

Abstract: A method and device includes advancing an anchor stent assembly and a second stent into a stenosed region of a blood vessel to protect or shield the vessel from possible blockage. The anchor stent assembly may include an anchor stent and a cover made of submucosal tissue (SIS). The cover is delivered in a dried, compressed, condition and is later softened and expanded by exposure to the flow of blood. The second stent may then be advanced within the cover and dilated to press the cover against the stenosed region of the vessel, thus protecting the vessel from emboli formed of stenosis breakage.

Abstract: An embolic protection device includes a foam body attached to a plurality of flexible struts. The foam body has a generally conical geometry and the bottom of the conical geometry having a generally conical recess. The filter portion has pores sized such that blood cells can pass through the foam body, but larger material such as objects would be trapped in the recess. Each strut is attached along the periphery of the foam body and extend from the first end of the foam body to a connection point located proximate the first end.

Abstract: A device for capturing emboli during treatment of a stenotic lesion in a body vessel is disclosed. The device comprises a base having expanded and collapsed states, and proximal and distal portions. The distal portion has a support portion configured to deploy in the body vessel when the base is in the expanded state. The device further comprises a filter portion disposed on the distal portion of the base. The filter portion includes a lip extending to a filter body to a filter end. The filter portion is configured to engage the support portion when deployed to define an opening of the filter portion for capturing emboli. The device further comprises a collector through which the base is slideably disposed for delivery and retrieval of the device.

Abstract: An embolic protection device for deployment in a body vessel is provided for filtering emboli within the body vessel. The embolic protection device generally includes a filter having a plurality of openings formed therethrough and an extraction element configured to be movable with respect to the filter between a non-extraction position and an extraction position. The extraction element is located distally of the filter when in the non-extraction position so as to allow the filter to open into an expanded state to collect the emboli. Additionally, the extraction element is disposed about at least a portion of the filter when in the extraction position so as to close the filter into a collapsed state and to permit the embolic protection device to be extracted from the body vessel.

Abstract: An embolic protection device including a core wire and a basket is disclosed. The basket includes struts and a filter portion formed from a cannula. The struts extend from a first end of the basket to the second end of the basket. The filter portion extends from the struts and is formed unitarily therewith. The filter portion extends between a middle portion of the basket and the second end of the basket and includes openings in the cannula configured to allow the passage of blood cells therethrough.

Abstract: An embolic protection device includes a basket formed from flexible struts. The struts extend from a first end of the basket to the second end of the basket. The struts form a middle portion of the basket where the struts extend substantially perpendicular to a longitudinal axis, running between the first and second end of the basket.

Abstract: A system for permitting substantially bloodless percutaneous entry into an artery or vein of a patient. The system comprises a needle assembly, a needle hub attachment assembly having a hemostatic segment, and a wire guide inserter (curve straightener) or a wire guide holder also having a hemostatic segment. The components are assembled in a leak-free arrangement, and a fluid passageway for withdrawing blood is established through the system. Each of the hemostatic segments opens to permit passage of a wire guide therethrough, but re-seals to prevent flow of blood therethrough. The needle hub attachment assembly preferably includes a fluid-receiving chamber to permit the clinician to see the first squirt of blood as it enters the system.
